PRINCETON BOROUGH — A Trenton woman who allegedly attacked her ex-boyfriend with a knife outside his home was arrested after both had struggled for the weapon Friday evening, police said.

Dyasia Harrell, 19, was visiting her ex-boyfriend who lives in the township just before 8 p.m. The victim crossed into the borough while walking on John Street near Clay Street, which is when police said she confronted him.

“Apparently he was walking from his car going to his residence and she followed him and attacked him,” Capt. Nick Sutter said.

Harrell allegedly brandished the knife and threatened to kill the man, leading to the fight over the weapon. The two sustained minor cuts to their hands during the struggle, police said.

While the man refused medical treatment, Harrell was taken to the University Medical Center of Princeton at Plainsboro before being released on $10,000 bail. Harrell was charged with aggravated assault, terroristic threats and unlawful possession of a weapon.
